That is a terrible thing to have happen. Sorry to hear that he passed away. At least he didn't have to suffer a long time. My condolences to his family and their loss.

I had with a coworker who had a stroke after just 3 months of working with him in the field. He was only a 35 years old Mexican guy. Younger than I was at the time. He's still alive, but it's devastating all around.
